• SV193 0.8x focal reducer can take dazzling celestial photos without worrying about the distortion of the star points on the edge of the photo;
• The front is a standard 2-inch socket for connecting the main lens. The rear is a M48x0.75 thread for connecting the camera mount. Supports full-frame cameras
• The SV193 can be connected to a standard 2" filter thread to add the light pollution filter you need；
• The 0.8X defocus system shortens the exposure time. It can meet the needs of astronomical photographers who need sufficient exposure in a short time;

• SV209 0.8X focal reducer/field flattener is designed specifically for prime focus astrophotography with the SVBONY SV550 122mm f/7 apo refractor;
• SV209 field flattener can correct the defect of field curvature of the user's shooting target; improve the imaging quality and shooting efficiency of the edge of the field of view;
• SV209 0.8x focal reducer converts the 854mm focal length f/7 refractor into a 683.2mm f/5.6 system for faster and wider field astronomical and terrestrial photography;
• In addition to reducing the focal length of the telescope and thereby increasing the photographic speed, the flattens the normal field curvature inherent in refractors. This provides images that are sharply focused out to the corners of DSLR and CCD imaging chips;
• SV209 0.8x reducer has a metric 63x1 thread; the telescope reducer flattener screws into the focuser to ensure a secure connection;

• SV211 dovetail base comfortable and convenient carrying handle. After the combined installation, the large-aperture telescope can be easily carried and moved;
• SV211 finder scope mount bracket the length is 203mm, with 2 M6 mounting screws, 4 M4 set screws, and 1 M5 wrench, which can be easily installed and removed;
• SV211 dovetail base full CNC integrated finishing anodized aluminum, not easy to damage;
• It can reduce collision and wear when taking the telescope somewhere;

• CNC hollow structure; SV225 altazimuth mount adopts hollow structure; reduce the weight(2.34Kg); convenient for you to carry out; light weight
• Fine adjustment shift; SV225 alt-az mount can fine-tune the telescope to meet your adjustment efficiency in different scenarios
• Variable speed gear; SV225 alt-azimuth mount is variable speed gear slow motion controls on both axes to let you smoothly follow the motion of the moon and planets
• Load capacity; with a payload capacity of 10kg; even light weight; the SV225 alt azimuth mounts will match well with the telescope; camera and so on
• Applicable scenes; SV225 alt-az mount is suitable for many senorios; like astronomical visual observation and surface observation

• SV209 is a special field flattener for SV550 80F6 OTA, which can effectively improve the image quality problem of SV550 OTA fringe field curvature; At the same time, the focal length and focal plane position of the primary mirror remain unchanged;
• The package of SV209 is equipped with an M63 extension tube and an M48 adapter ring to ensure that the back focal length of the flat field mirror is the astronomical conventional 55mm length;
• The effective field of view of the 45mm large target surface supports not only half-frame cameras; but also full-frame cameras;
• Built-in 2-inch filter mounting thread; supports 2-inch filter installation; customers do not need to buy a filter adapter ring separately;
• Maximum working distance from the M63x1 internal thread: 103 mm - space enough for almost all adaptations.

Notice: Since the SV550 80 APO is designed with f/6 focus ratio. When reducing the focus further, the image quality will not be guaranteed. This is why we produce 1.0x flat field instead of 0.8x.

• SV211 handle suitable for OTA SV503 (70 F6；80F7) SV550 (80F6) by adjusting the position of the handle, improve the safety factor of the product installation process;
